1. The nurse is reviewing the hot/cold theory of health and illness. Which statement best describes the basic tenets of this theory?
- A. The causation of illness is based on supernatural forces that influence the humors of the body.
- B. Herbs and medicines are classified based on their physical characteristics of hot and cold and the humors of the body.
- C. The four humors of the body consist of blood, yellow bile, black bile, and phlegm.
- D. The treatment of disease consists of adding or subtracting cold, heat, dryness, or wetness to restore the balance of the humors of the body.
Correct answer: D
Rationale: The hot/cold theory of health and illness is based on the four humors of the body: blood, phlegm, black bile, and yellow bile. These humors regulate the basic bodily functions, described in terms of temperature, dryness, and moisture. The treatment of disease in this theory involves adding or subtracting cold, heat, dryness, or wetness to restore the balance of the humors. Choice A is incorrect as the theory is not based on supernatural forces but on the balance of bodily humors. Choice B is incorrect as herbs and medicines are not classified solely based on their physical characteristics of hot and cold in this theory. Choice C is incorrect as the four humors are blood, phlegm, black bile, and yellow bile, not spiritual connectedness or social aspects. Therefore, the correct choice is D, as it accurately reflects a foundational tenet of the hot/cold theory of health and illness.
2. The nurse is examining a 2-year-old child and asks, "May I listen to your heart now?"? Which critique of the nurse's technique is most accurate?
- A. Asking questions may enhance the child's autonomy.
- B. Asking the child for permission helps develop a sense of trust.
- C. This question is an inappropriate statement because children at this age like to have choices.
- D. Children at this age like to say, "No."? The examiner should not offer a choice when no choice is available.
Correct answer: D
Rationale: Children at the age of 2 often like to assert their independence by saying "No."? In situations where there is actually no choice available, offering a false choice can lead to a lack of trust. It is important not to offer a choice when there isn't one, as doing so may undermine trust. While asking for permission can enhance autonomy and trust, offering a limited option like, "Shall I listen to your heart next or your tummy?"? may be a better approach. Therefore, the correct critique of the nurse's technique in this scenario is that children at this age tend to say "No,"? so the examiner should avoid offering a choice when there isn't a real alternative.
3. When performing a physical assessment, what technique should the nurse always perform first?
- A. Palpation
- B. Inspection
- C. Percussion
- D. Auscultation
Correct answer: B
Rationale: During a physical assessment, the nurse should always begin with inspection. The sequence of techniques for physical examination is inspection, palpation, percussion, and auscultation. These skills are performed in a specific order, except for the abdominal assessment where auscultation precedes palpation and percussion. Inspection allows the nurse to observe and gather initial information without direct contact. It is a crucial step that provides valuable insights before proceeding to palpation, percussion, and auscultation. Therefore, choice B, 'Inspection,' is the correct answer. Choices A, C, and D are incorrect because they should follow inspection in the sequence of a comprehensive physical assessment.
4. Which bloodborne pathogen is the most virulent? (Choose the BEST answer.)
- A. HCV
- B. HPV
- C. HIV
- D. HBV
Correct answer: A
Rationale: The correct answer is HCV (Hepatitis C Virus). Hepatitis C is considered the most virulent bloodborne pathogen, being 100 times more virulent than Hepatitis B. HPV (Human Papillomavirus) is a sexually transmitted infection but is not a bloodborne pathogen. HIV (Human Immunodeficiency Virus) affects the immune system but is not as virulent as Hepatitis C in terms of bloodborne transmission. HBV (Hepatitis B Virus) is less virulent compared to HCV in the context of bloodborne transmission.
5. Which vacutainer tubes should be used when a requisition calls for blood to be drawn for an H&H and glucose test?
- A. One light blue, one red
- B. Two lavenders
- C. One lavender, one grey
- D. One green, one red
Correct answer: D
Rationale: The correct answer is 'One green, one red.' An H&H test involves hemoglobin and hematocrit, which are components of a complete blood count and are typically drawn in a lavender tube. On the other hand, blood for glucose testing is collected in grey tubes. Therefore, when drawing blood for both an H&H and glucose test, one green tube for glucose and one red tube for H&H should be used. The other choices are incorrect because light blue tubes are used for coagulation studies, lavender tubes are for complete blood counts, and green tubes are for chemistry tests like glucose, while grey tubes are specifically for glucose testing.
